Application filed October 20, 1882. (No model.)

T all whom, it may concern: has fully passed the needle, and thusobviates Be it known that I, WINsLow R.

The operator is thus enabled to and State of Iowa, acitizen of the United turn corners and braid in curves with great Statesof America, have invented certain new facility and nicety.

The extended groove a sewing-machines it isfrequently necessary to holds the braid from moving sidewise until itturn the goods or move them so that the braid 10o may be attached invarious designs. The presser foot, by resting constantly on the goods,prevents the goods from being moved with facility for the purposereferred to.

To obviate the objection I employ the following means:

F is a presser-foot, and F foot bar.

G is an arm or lifter, the lower end of which is fitted nlovably uponthe square portion of the bar F, and the upper end of which is curved orbent to project horizontally away from the said bar, as shown.

H is a setserew passing through the lower part of the lifter G, andhaving its inner end or point in contact with the bar F, therebysecuring the part G adjustably to the bar F, or so that it may be movedup and down thereon and secured in any position in which it maybe set.

I is a slot in the faceplate. This slot is lo cated in the back of theface-plate, and the screw H passes through the slot I, as shown. By thismeans the exposed end of the screw H is conveniently accessible, and maybe made tighter loose and raised or lowered for the purpose of adjustingthe lifter Gvertically 011 the presser-foot bar.

J is the end disk of the horizontal shaft of the machine, and d is asmall pin or stud projecting therefrom. This pin is arranged directlyopposite the roller K, which vibrates the needle as the said shaft isrotated, and the upper or horizontal part of the lifter G is ar ranged,as shown, to be struck and raised by the pin (1 each time said shaft isonce rotated. By this means the presscr-foot will be raised from thegoods while the needle is in the goods, and the latter may then beturned on the needle as a pivot, thereby admitting of the goods beingturned with facility, so that the braid may be evenly stitched theretoin various patterns or designs.

It will be perceived that the lifter G may is the presserbe raised oradjusted either so as not to be struck by the pin d when no braiding isto be done, or that it may be so adjusted that its movement will begreater or less, as may be desired.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In an under-braider, a throat-plate constructed with a braid-passageand a needlehole, said braidpassage extending beyond said needle-hole,substantially as herein described, for the purpose set forth.

2. The combination, in an under-braider, of a throat-plate, A, having agroove, a, in its upper side to form the terminal end of thebraidpassage, with a needle-hole, 7), within said groove, said grooveextending beyond the needle-hole, and a cover or tongue, E, overlyingthe braid within said groove, substantially as herein specified.

8. The combination of the throat-plate A, having in its upper side thebraid-groove a, and the braid-pressing spring B, having therein aneedle-hole, and arranged substantially as shown and described withrelation to the needle, for the purposes specified.

4. The combination, with the braid-grooves of an nnder-braider, of aspring adapted and arranged to press the braid yieldingly on its passageto the needle, and the tongue E, having in its free or outer end a bevelor arch, c, substantially as and for the purposes specified.

5. The combination, in an under-braider, of the grooved throat-plate A,the spring B, the grooved shuttle-race slide D, and the tongue E, allarranged substantially as shown and described with relation to eachother, for the purposes set forth.
